Abstract: A battery housing for medical scooter includes a movable base provided with at least two battery compartments for each receiving a battery therein, an electrode contact provided at the bottom of each battery compartment to electrically connect to a positive or a negative electrode of the battery in the same compartment, and an electricity chamber for accommodating a charger and a power cord that could be easily pulled out to connect to an external AC power source for the charger to recharge the batteries. Two elastic conductive plates are provided below the battery compartments to contact with the electrode contacts, so that power could be supplied from the batteries to positive and negative power supply wires of the cart connected to the conductive plates. Drain holes are provided below the elastic conductive plates to protect the battery housing from damage due to accumulated water on the medical scooter.

Abstract: An electrical wheelchair includes a chassis to which a frame is pivotally mounted. Two casters are rotatably mounted to the frame. At least a resilient member is arranged between the frame and the chassis for supporting the relative position of the frame with respect to the chassis. The resilient member can be deformed to change the relative position of the frame with respect to the chassis to allow the wheelchair to climb over raised surfaces of different heights. The deformation of the resilient member also stores energy therein which may be released when the wheelchair is about to reach the raised surface for enhancing the wheelchair to move over the raised surface. Further, the resilient member also functions to absorb shock caused by the wheelchair moving down a step-like raised surface.

Abstract: A miracle curb climber includes a casing having a top connecting bolt for screwing to a front or a rear axle of a walking aid, such as a handcart, a wheelchair, an electric wheelchair, a wheeled power chair, etc., at least one front pilot wheel and at least one main land-contacting wheel mounted into front and rear end of the casing, respectively, and at least one relaying wheel mounted in the casing between the pilot wheel and the land-contacting wheel. The front pilot wheel and the relaying wheel have diameters smaller than that of the main land-contacting wheel and are suspended in the air in front of the main land-contacting wheel, enabling the main land-contacting wheel to smoothly climb up a raised obstacle, such as a curb or a threshold, at a reduced angle of climbing without causing violent vibration or sway of the walking aid.

Abstract: An articulated front axle assembly for an electric invalid power chair is provided. The assembly mainly includes a guide bar fixedly connected at an upper end to a lower end of a front direction-control handle of the electric invalid power chair and at a lower end to an n-shaped articulation member or a pivot shaft, and a front axle pivotally connected at a predetermined position to the articulation member or the pivot shaft. Two front guide wheels are separately connected to two ends of the front axle.

Abstract: A headrest for simple-structured seat is provided. The headrest includes at least one pair of bar receivers and at least one pillow. Each of the bar receivers includes two wing portions and defines an insertion hole between the wing portions. The wing portions are provided with a plurality of fixing holes via which screws may be threaded into a rear side of a back of the seat so as to connect the bar receivers to the back of the seat. The pillow includes at least one pair of elastic bars downward projected therefrom for inserting into the insertion holes defined by the bar receivers on the back of the seat. The elastic bars automatically extend outward to tightly press against inner walls of the insertion holes and thereby firmly hold the pillow of the headrest to the back of the seat. The headrest may be easily installed on a seat for all kinds of vehicles.

Abstract: A fast-dismountable covering panel for mounting on a chassis of an electric cart is provided. The covering panel includes a front round opening and a rearward opened elongate opening opposite to the round opening. The elongate opening is adapted to engage with a handlebar stem upward extended from a front end of the chassis. A very narrow slit is provided along a centerline of the covering panel to extend between the round opening and the elongate opening, allowing the covering panel to be elastically stretched apart at the elongate opening along the slit for the handlebar stem to move forward along the slit into the round opening and causing the covering panel to cover and be screwed to a top of the chassis. A gasket is removably engaged with the slit to seal the same. Footrest panel, mat fixing strips and mat may be detachably connected to the covering panel and the covering panel may be mounted onto the chassis after the latter has been fully assembled and passed quality inspection.

Abstract: An electrical wheelchair includes a chassis on which a seat is mounted. The chassis has a double-framed structure including a primary frame and a secondary frame pivotally connected to each other so as to be rotatable with respect to each other about a first rotational axis. Two driving wheels are mounted to the primary frame and independently driven by motors. Two rear guide wheels are rotatably and swivellingly mounted to the primary frame. The secondary frame has a front edge frontward extending beyond the primary frame with two front guide wheels rotatably and swivellingly mounted thereto whereby the front guide wheels are capable to orbit about the driving wheels by means of the pivotal connection between the primary and secondary frames so as to provide the front guide wheels and the driving wheels with excellent surface compliance when the wheelchair is moving on an uneven surface.

Abstract: A detachable framework for an electric cart including a first chassis part, a second chassis part, and a connecting pin. The first chassis part has a steering handle for controlling a moving direction of a front wheel of the electric cart, a connecting pin receiver upward extended from a rear center thereof, and a connecting beam extended across a lower rear end thereof. The second chassis part has rear wheels and a driving mechanism mounted thereto and includes two receiving heads at its two lower front ends for receiving two ends of the connecting beam therein, a supporting post upward extended from a middle front thereof and having a first positioning screw on its front wall, and a seat post connected to a front top of the supporting post to locate immediately above the connecting pin receiver and having a second positioning screw provided on a front wall thereof.

Abstract: An electric cart includes a first chassis member having a pivot axle fixed thereon and a second chassis member having two spaced recesses formed thereon to rotatably receive the pivot axle therein so as to form a rotatable coupling therebetween. An upright post is fixed on the first chassis member to support thereon a seat. Two spaced lugs is provided on the post. The second chassis member has an upright rod to support thereon an abutting member having an end sized to be received between the lugs. A cushion pad may be fixed to the end of the abutting member to provide a non-direct cushioned contact engagement between the upright post and the abutting member. The weight of the chassis members rotates the chassis members about the pivot axle in a direction to force the end of the abutting member to abut against the post.

Abstract: An automatically deployable vehicle stabilization system comprising a pair of stability arms pivotally coupled to a vehicle frame. The stability arms are fixedly coupled to a pivot bar. A drive mechanism interconnecting the pivot arms with a steering column of the vehicle causes the stability arms to pivot into extended positions when the front vehicle tire is turned. The stability arms prevent the vehicle from overturning when in operation. When the front vehicle tire is returned to its normal position, the stability arms retract so they do not bump into low-profile objects in the path of the vehicle. Alternatively, the stability arms can be locked into extended positions, if desired.

Abstract: The four-wheeled T-handlebar carriage is deliberately designed for the senile and the invalid. The rider can easily operate the carriage with the aid of the T-shaped steering handlebar and drive safely without fear of overbalancing while the provision of four wheels ensures extraordinary stability for the carriage body. A safe and pleasant drive on the carriage is therefore attainable to all the senile and invalid population.
